    摘要: The control path of the switch (I) comprises an input stage (T2, T1) having an input (H) coupled to the input (E) for the control signal and having its output coupled to the control electrode (G) of the switch (I). A protection circuit (D1, Z2) coupled between the load (C) and the control path includes a threshold effect component (Z2) and a decoupling element (D1). On being made conductive by the current that results from a surge generated in a circuit of the load (C), the protection circuit (D1, Z2) is coupled to the input (H) of said input stage (T2, T1) to act on said switch (I) in the same way as a control signal for the switch (I). In this manner, the control path prevents current in the load (C) from dropping off suddenly.
